Method for automatically adjusting track gap of permanent magnet array
The invention discloses a method for automatically adjusting a track gap of a permanent magnet array. The method is characterized by comprising the following steps of: calculating deformation quantities of a sky beam and the permanent magnet array and displacement quantity of the permanent magnet array relative to the sky beam in different environments; the above data are analyzed, kidney-shaped holes for reducing gap changes are formed in the permanent magnet array, meanwhile, pre-pressing blocks are placed between the permanent magnet arrays, when the sky beam and the permanent magnet array deform, the pre-pressing blocks placed between the permanent magnet arrays apply opposite force to the permanent magnet arrays, stress borne by the permanent magnet arrays is equal, deformation quantity is the same, and the permanent magnet arrays are not prone to deformation. Therefore, the distances between the permanent magnet arrays are small in change and are the same. According to the invention, the space change of the permanent magnet array caused by deformation of the sky beam and the permanent magnet array when the sky beam expands with heat and contracts with cold due to environmental influence can be effectively avoided, and a guarantee is provided for stable operation of a train.
一种自动调节永磁阵列轨道间隙的方法，其特征是：通过计算得出在不同环境下天梁和永磁阵列的形变量、永磁阵列相对于天梁的位移量；分析上述数据将永磁整列上开设减少间隙变化的腰孔，同时在各永磁阵列之间放置预压块，在天梁和永磁整列都发生形变时，在各永磁阵列之间放置的预压块将给永磁阵列相反力，使各永磁阵列所受应力相当，形变量相同，从而使各永磁阵列之间的间距变化小且相同。本发明可以有效地避免天梁受环境影响发生热胀冷缩时，天梁和永磁阵列发生形变导致永磁阵列间距变化，为列车的稳定运行提供保障。
